Particle size analysis results from the VA-Clarke-03 core, Cherry Hill quadrangle, Dinwiddie County, Virginia (ver. 1.1, May 2025)
The dataset documents results from particle size analysis (PSA) conducted on a suite of sediment samples from the VA-Clarke-03 core, Cherry Hill quadrangle, Dinwiddie county, Virginia [36.931926, -77.566802]. The 44-foot-long core was collected on 05/16/2023 using the North Carolina Geological Survey Geoprobe. The core was collected from sands and gravels of the uppermost coastal plain that host the Old Hickory heavy mineral deposit. Because host sediments are non-fossiliferous, there is little consensus as to their age, stratigraphic position, or nomenclature. Current mapping assigns host sands and gravels to two units in the upper part of the Pliocene to Pleistocene Chesapeake Group. In the lab, the core was analyzed using the USGS GeoTek multi-sensor core logger system housed in the Florence Bascom Geoscience center, Reston, VA. After Geotek analysis (Carter and others, 2024), sediment samples were collected from the core for PSA, detrital zircon analysis, and 26Al/10Be cosmogenic burial dating. This work is a collaboration with the Virginia Department of Energy, Geology and Mineral Resources Program and the North Carolina Geological Survey through the USGS National Cooperative Geologic Mapping Program, southeastern Atlantic Coastal Plain Working Group, and the USGS Earth MRI Program.

Particle size distribution data from U.S. Army Base Fort Drum, Jefferson County, New York, 2023
공공데이터포털
The dataset documents results from particle size analysis (PSA) conducted on a suite of sediment samples from U.S. Army Base Fort Drum, Jefferson County, New York. Most of the PSA samples were collected from representative cells in a series of five portable optically stimulated luminescence (OSL) grids, here denoted G1 through G5, to constrain variations in grain size. These samples were also collected in conjunction with OSL for absolute chronology. In the lab, PSA was conducted using sieving equipment housed in the Bascom Laser Diffraction Sedimentology Laboratory at the U.S. Geological Survey in Reston, Virginia. Subsamples from G3 and G4 were also analyzed for elemental concentrations via inductively coupled plasma - mass spectrometry (ICP-MS). This work is a collaboration with the Fort Drum Environmental Division and the Fort Drum Cultural Resources Division and was funded by the National Cooperative Geologic Mapping Program.

Particle size and portable X-ray fluorescence (pXRF) data from U.S. Army Base Fort Drum, Jefferson County, New York, 2024 (ver. 1.1, May 2025)

The dataset documents results from particle size analysis (PSA) and portable X-ray fluorescence (pXRF) analysis conducted on a suite of sediment samples from U.S. Army Base Fort Drum, Jefferson County, New York. Samples denoted by "FD24-Sed" were collected to obtain representative samples of surficial geologic map units, and samples denoted by "FTD-WS-MW" were collected during a collaborative vibrasonic coring campaign with contractors as part of a Fort Drum Environmental Division project. Laboratory work was conducted using sediment analysis instrumentation housed in the Bascom Laser Diffraction Sedimentology Laboratory at the U.S. Geological Survey in Reston, Virginia. Samples were first wet sieved at #230 mesh (63 µm) to determine percentages of fine and coarse material. PSA was conducted using dry sieve analysis for samples mainly comprised of coarse material (i.e., sands); several samples were sieved at 1/4 phi intervals for investigative purposes while the remaining samples were sieved at 1/2 phi intervals for general classification. The remaining samples, mainly comprised of silts and clays, underwent laser diffraction PSA using a Beckman Coulter LS 13 320 XR particle size analyzer. pXRF analysis was conducted on representative subsamples from each original (unprocessed) sample using a Bruker S1 Titan instrument. This work is a collaboration with the Fort Drum Environmental Division and was funded by the National Cooperative Geologic Mapping Program. This Data Release was revised to v1.1 in April 2025 to include updated statistics data for laser diffractometry results contained therein. No other changes to the data release were made for v1.1.

The influence of tropical and extratropical cyclones on coastal wetlands and marshes is highly variable in both space and time and depends on a number of climatic, geologic, and physical variables. The impacts storms can be either positive or negative with respect to the wetland and marsh ecosystems. Small to moderate amounts of inorganic sediment added during storms or other events helps to abate pressure from sea-level rise. However, if the volume of sediment is large and the resulting deposits thick, the organic substrate may compact causing submergence and a loss in elevation. Similarly, thick deposits of coarse inorganic sediment may also alter the hydrology of the site and impede vegetative processes. Alternative impacts associated with storms include shoreline erosion at the marsh edge as well as potential emergence. Predicting the outcome of these various responses and potential long-term implications can be obtained from a systematic assessment of both historical and recent event deposits. The objectives of this study are to 1) characterize the surficial sediment of the relict to recent washover fans and back-barrier marshes, and 2) characterize the sediment of 6 marsh cores from the back-barrier marshes and a single marsh island core near the mainland. These geologic data will be integrated with other remote sensing data collected along Assateague Island, Maryland / Virginia and assimilated into an assessment of coastal wetland response to storms.
